AbstractUsing the National Longitudinal Study of Adolescent Health (Add Health), the current study applies a general biosocial theoretical model to polydrug use and associated substance-related problems. Along with measures of molecular genetic polymorphisms, neurocognitive skills, self-control, and environmental pathogens a recursive path modeling strategy was used to empirically examine the relations between these biosocial measures and polydrug use, alcohol, and drug-related problems in a subsample of 1136 adolescent males (Mean age = 21.96, SD = 1.73). Results supported the main predictions of the biosocial model finding significant path coefficients across key constructs. In particular, the role of poor self-regulation was found to be sturdy across path models.
